If you have a camera that has been patched for the view/index.shtml vulnerability, follow these guidelines to maintain security:
An attacker with physical or LAN access could flash an older, vulnerable firmware version onto the camera, re-enabling the flaw.
Some patched versions only blocked view/index.shtml but left other endpoints like view/index.asp or cgi-bin/admin.cgi vulnerable. Security researchers found that the patch was often superficial.
